Susan Boyle has canceled her appearance on Dancing with the Stars because of a throat infection, a show rep tells TVGuide.com.

The Britain's Got Talent sensation was scheduled to perform on Tuesday's results show, but has been laid up in her native Scotland. ABC declined to comment about a replacement or whether Boyle will reschedule.

This would've been Boyle's second Dancing visit: She performed on the show last November ahead of the release of her debut album, I Dreamed a Dream. The disc was the top-selling album of 2009 worldwide.
